My 74 1.8 L-Jet is giving me trouble, At start up, engine cold, it will idle rough (400-500 rpm) and seems to be loading up?, after 3 or 4 minutes the rough idle goes away and it will idle at 900 rpm's, but if I ease into the throttle it cuts out around 2800-3500 rpms, but I can rev it to red line. after driving it 2 or 3 miles it seems to clean out and runs great, however it will from time to time die when I have the clutch in while stopping.
Where should I start looking
